where can I find more info about links

[livexia]

Links is an important part of neorg, but I can't find anything about it on tutorial or
wiki. In the tutorial videos the link seems work with concealer, but does not work in mine. Anywhere I can find information about how to write a link? Also current documents or wiki is more about how to config neorg rather than how to write norg(grammar).
